Representing Systems with Models

A model is an abstraction of a system that offers insight into that system's properties, such as behavior, appearance, or cost. Modeling is a common practice that is shared by most engineering disciplines and includes electrical circuit design models, three-dimensional computer-aided design models, software design models, and analytical models used to support power, thermal, structural, and embedded real-time analysis. Modeling systems are becoming increasingly important to the practice of systems engineering as a means to enhance quality, productivity, and innovation, as well as reduce the cost and risk of systems development. Different types of models are needed to represent systems in support of the analysis, specification, design, and verification of systems. This knowledge area provides an overview of models used to represent different aspects of systems.
